I'm trying to understand the concept of surrender. How does Chapter 26 describe the act of surrendering one's ego to Sai Baba?

Chapter 26 provides a powerful depiction of complete surrender to the Guru. The devotee expresses this by praying to lay their ego at Baba's feet, asking Him to take away all body-consciousness and the associated experiences of pleasure and pain. The surrender is so total that the devotee asks to be moved like a puppet according to Baba's will, with a restrained mind. As described in this chapter, the ultimate act of surrender is the plea for Sai Baba to Himself become the devotee's very 'me-ness,' taking on the experiences of life so the devotee no longer worries about them. This signifies the complete dissolution of the individual ego into the divine.
